Long before I changed my official identity documents, I came out at my workplace, explaining my situation and that my preferred pronouns are male. Now, people rarely misgender me, and it's a rarer occasion still when I have to come out as trans or correct the pronouns by which people refer to me. Everyone just assumes I'm male by default, and I don't often correct them, even though that view is wrong. At best, it's near-sighted.
